Original application filed September 13, 1910, Serial No. 581,915. Divided and this application filed May 18, 1911. 7- Serial No. 627,957.

o 'l'wlzomt may concern." I moon that l, LOUIS J. FLT-WI, a citithe United States, residing at Chlcago, the county of Cook and State of Illinois, have invented a certain new and 1. 'rful Imp ovement v in. Intermpters, of lSJlCl1 the tollowing' is a full, clear, concise, ill exact description, reference being had to the accompanying drawings, forming a part "i this specification.

and. has for its object'thcqwrovh a '1 improved device of this nature see good insulating characterish can beoperated at a high rate i :hanical causes, but which is at canoe tune economical to manufacture.

"' additional object is to provide an inter- Which has a quick break and also mechanical pounding on the plati 1 contacts in closing the circuits.

The subject matter of this application is a division of my co-pending case for magneto generators; Serial No. 581,915, filed September id, 1910.

In the accompanying drawings, which form a p t this specification, Figure 1 lon udinal elevation taken through it the axis of the machine; Fig, 2 is a sectional view on i "use d0Z of Fig. l; and 3 is a detailed tacts 3.114. tions,

one of the interrupting projem -cruptcr is shown mounted upon armature shaft 44 of a macu rent it is desired to control. 53 are mounted so as to shaft 44, one of said spring ctrically connected with a bushingsuch as 43. A disk material also is provided, i said spring, plates except at t point The inner spring cally connected to a sleeve 4:1 "a s aft and bushing 13. l end of the shaft 44 'is a z carries an annular disk of, inf 52", provided with projecthe planes of the ro3actions sepaelby periodically plane inidwa sprite so rate the cont-act between ,1 invention relates to my improved ill-- tnout iinury from either elc-' pcctive View of the spring con v dish mounted in a passing between the Wiping plates 55, which are carried by the outer extrcmitics of the springs 53.

Carried on a flange of the ring 11 a plate 12 Within which is provided a con denser 65,- "which is Wound upon but insulated from the log 59 on the inner side of said plate, The condenser is connected across the plates 53 for the purpose of reducing the sparking upon breaking the circuit. Such connections are made to one side of the condenser by means of a wire 66 leading to a binding post 67, which is grounded upon, the frame of the machine, and thus connected with the inner plate 53 Whichis in contact with the grounded sleeve 41. The other side of the condenser is connected to the outer plate 53 by means of a brush 61 which is pressed against a collar 55 by a spring 62 on t-hcend of the shaft 44,

from which thecurrent passes to the lug 59 and the post 60. Carried by the post is a suitable nut 63, which binds the Wire 64 leading to the other side of the condenser,

It Will thus be seen that applicant has provided a cheap and eflective interrupter capable of producing a large number of interruptions in a circuit in. which it may be connected. Moreover, as tips 55*- are worn away by passing over the projections 56,the springs 53 force fresh surfaces into contact, giving an automatic adjustment of the spark'points' to compensate for wear and i allowing the plates 55 to be entirely used up before needing to be renewed.

-Having thus described my invention what I claim as new and desire to secure by Letters Patent is: v

1. An interrupter comprising a rotary shaft, a pair of contact springs carried by and rotating with said shaft, and a ring supported in position surrounding said shaft, but with space between the ring and shaft, in which space said contact springs rotate, said ring and springs beingprovided with cooperating devices by which the springs are caused to make and break con tact with one another.

2. An interrupter comprising a rotary shaft, a pair of springs mounted upon and rotating with said shaft, a rin supported in position surrounding the shat, but with space between the ring and shaft, in which space said springs revolve, said ring being provided with radially extending projections arranged to cooperate with said springs to cause contact and separation of the same,

The combination of a rotary shaft, a

pair of springs mounted upon and rotating same.

4. The combination with a rotary shaft 01 a pair of contact members mounted upon and rotating with said shaft, a ring surrounding said shaft but with space between said ring and shaft, in which space sald contact members revolve, said ring and con tact members being provided with-cooperatin'g instrui'nentalities to bring about a make and break action of said contact members, and means whereby said'ring may be given a rotary adjustment. A

5. The combination of a rotaryshaft, a pair of spring contact members mounted upon and rotating witn said, shaft, an in sulating ring surrounding said shatt, but with space-between said ring and said shaft, in which space said contact members revolve, said ring being provided with radially extendingprojections adapted to bring about a make and break action on the part of said contact members, said ring; Joeing valso provided with segmental slots and pins extended through said slots.

6. An interrupter comprising in combination, a rotary shaft, a pair of springs Carried on said shaft and normally in contact with each other, one of said springs bein' 'gmeans to-periodically separate said sprin s.

7. An interrupter comprising in combination, a rotary shaft, a PQdLOf springs carried on said shaft being normally in oontact with each other, one of said springs being in electrical contact with said shaft, an insulating sleeve surrounding said shaft separating the second one of said springs from. the shaft, a conducting sleeve overlying said insulating sleeve and making electrical contact with the second oneoit said springs, and means for periodically sepa rating said springs.

8. A circuit interrupter comprising in combination, a pair of rota'tabl mounted springs, each of said springs having a contact point and a wiper plate thereon, and

- one or more prongs adapted to pass between said wiper plates to separate said contacts upon each revolution of said springs.

9. A circuit interrupter comprising in combination, a pair of springs, each 0t which carries a contact and a wiper portion, and means for periodically inserting an element between said Wiper portions to sepa rate said contacts.

In witness whereof, I hereunto subscribe i s LYDA Jones,
